Obviously we have someone here who thinks motorcycling should be outlawed. In about 100,000 miles there was one foreign object impact that would have been able to cause me trouble if I was helmetless. But then that was at triple the speed than I would ride without a helmet. Also a hit to the body could as well lead to an accident, but there's no law for full armor. That's a contradiction in itself. Take a look at Bobby's figures about motorcyclist injuries and fatalities. No one in a sane state of mind could "choosing to ride" call "doing reasonable things to mitigate risk".
